    A React Native application running on an Android emulator or a physical phone can not connect to the backend on localhost. To fix this problem, it is necessary to run the backend application on your local IP address.

    It seems, you didn't change yourIp in environment.js.

    Can you do these steps, sequentially.

    If it is not work, can you run it in android studio?

    That IP listed in the screenshot is my local IP. I followed those steps exactly.

    I would expect that the solution should work out of the box and that I should have to resort to Android Studio to make it work.

    Is your mobile app runs at 19006 ?

    It should be run at exp://${yourIP}:19000 .

    By the way we have added how to run react native in androd studio to the documentation. https://docs.abp.io/en/abp/8.1/Getting-Started-React-Native If you want to check.

    If still not works, can you create a new application in 8.0.5 and check what is difference with your application.
